How will this device affect the car battery when left plugged in and not charging a device?

I leave mine plugged in all the time with the blue light still on and have had no problems but my car doesn't sit for more than a couple days without being started.

It's been plugged into our E350 van for over 2 weeks without starting the vehicle and it started up just fine.

If the blue LED light remains on when you remove your key from the ignition, it will drain power from you car battery - you should unplug it. If the blue LED light does not stay on when you remove your key from the ignition, your car battery will be fine.

It Doesnt. You will need to unplug it or else your battery will drain just like mine.

It doesn't charge, it's an inverter which means it uses your car battery to run electronics that would normally plug into your home outlet. It only works when connected to a car battery.

I leave mine plugged in to the car charger all the time. I can not speak to removing the battery, since I believe it is sealed. But it works great for streaming the music apps on my phone.

Just FYI, it doesn't damage your iPhone to leave it plugged in when it is full. It knows when the battery is full, and stops charging it. So no damage to battery.

We leave plugged in most of the time but it holds a charge indefinetly unplugged. I hope it helps.

All depends on how you connect it. If you are using the power ports in the car, some shut off when the vehicle is turned off some do not. Mine is wired directly to the battery.

Yes I leave it plugged in all the time but of course when the car is off it is not providing ant power.

Yes, the pad needs to be plugged in to work. If you tried to charge in the car, it would slide off the pad. Don't think car would be practical.

If I charge this and leave it in my car, as back up, will it drain faster under particular conditions?

Think instructions say leave plunged in whenever car not in use. Left mine plugged in during winter.

Well, I believe that anything using power from your car battery will drain it over time but I have used this product for up to 45 min with the car off and not have a problem. I wouldn't recommend doing it for extended times though. Yes, it works without the car being on.

I believe just like any re-chargeable device (Phone, Tablet, speakers etc...) the battery will become charged as the device is being used.To the best of my knowledge I believe that it uses the AC power. Never the less, the device still receives an increase in 'charged power' as you continue to use the device, as long as it's kept plugged in to an active outlet. I hope this helps.

IF any laptop doesn't have a battery than the plug component may be disconnected as well. Not positive though. It depends on the car some fuses run when the car is off interior lights etc. My Audi's CIG lighter where I plug this device into does not. Sorry

Yes, it does work. The disadvantage is that you have to leave it plugged in all the time. If the plug is in an inconvenient place, you may hit it with your knee or other body part. Also, i'm not sure whether it uses power when the car is off. If it does, it could drain your battery over time.

When you charge the device, it will be automatically turned off...you have to reconnect it after it is being charged!

As in "If your car battery gets low will this shut down?" If that's what you mean then no, it doesn't. If the device doesn't receive the charge it needs to run, however, it will shut down. Your car battery won't drain with this turned on as long as your engine's running, thus, keeping your car's battery charged.
